Build large, optimized, multi‑scene worlds with studio‑grade workflows.
Legacy Weaver is a professional, modular world‑building and streaming system for Unity. It enables developers to create large, optimized, multi‑scene environments with clean workflows, audit‑safe metadata, and a pipeline‑independent architecture (Built‑in, URP, HDRP). The system is designed to bring studio‑grade world‑building workflows to every Unity developer.
